MAX7316 Datasheet | Maxim Integrated

.. 19-3055; Rev 1; 4/04 10-Port I/O Expander with LED Intensity Control and Interrupt General Description The MAX7316 serial interfaced peripheral provides microprocessors with eight additional I/O ports plus one output-only port and one input-only port. Each I/O port can be individually configured as either an open-drain current-sinking output rated to 50mA at 5.5V or as a logic input with transition detection. The output-only port can also be assigned as an interrupt output for transition detection. The outputs are capable of driving LEDs, or can provide logic outputs with external resistive pullup up to 5.5V. Eight-bit PWM current control is available for all nine...
